RADVISION ANNOUNCES INDUSTRY'S FIRST

VIDEOCONFERENCING NETWORK APPLIANCE

New INVISION Product Line Integrates All

Videoconferencing Functionality Into Single Plug-and-Play Device


Glen Rock,  New  Jersey,  November  4, 2002 --  RADVISION  (NASDAQ:  RVSN) today
announced  its  INVISION  product  line,  the  industry's  first  ever  suite of
videoconferencing  network  appliances.  Unique in the  industry,  the  INVISION
family of products  provides IT managers  with  plug-and-play  devices  that are
easily   ordered  and  deployed  into  any   enterprise   network  for  turn-key
videoconferencing over IP and ISDN.

"Network Appliance" is a general product category for standardized  devices that
are preconfigured, scaleable, and designed to be plugged into a network for easy
deployment and management. INVISION features the full functionality of an entire
IP/ISDN  videoconferencing  infrastructure,   from  centralized  management  and
multipoint conferencing to gateway services and value-added applications,  in an
integrated, easy-to-order and easy-to-install device.

"As IT managers begin to layer videoconferencing over their other communications
applications,  there  is  increasing  demand  for  a  videoconferencing  network
appliance that is  preconfigured  and easily  integrates into an IP network with
full ISDN technology  support," said Roopam Jain,  strategic  analyst at Frost &
Sullivan,  a leading  industry  consultancy.  "With the INVISION line of network
appliances,   RADVISION  has  leveraged  its  leadership  in   videoconferencing
infrastructure to be the first-to-market with an off-the-shelf network appliance
that  bridges  the  legacy  world  of  ISDN  with  today's  IP-based   converged
communications network."

"Until today's launch of the INVISION product line,  videoconferencing  products
were  complicated  to  order  and  deploy  and  required   extensive   technical
configuration  by the  reseller  or end user,  which  was a  classic  sign of an
emerging technology sold to early adopters," said Gadi Tamari, CEO of RADVISION.
"In rolling out the industry's first network appliance, we are preparing for the
next phase of  videoconferencing,  one in which we expect to see  strong  market
growth and broad videoconferencing  deployment throughout enterprises because of
its ease of use."

"Responding  to market  requests for an easy to order and install  solution,  we
developed  a  suite  of  standardized,  off-the-shelf  network  devices  that IT
managers  can simply plug into the  corporate  LAN and use to quickly  implement
videoconferencing,  either as a stand  alone  solution  or  bundled  with  other
IP-based solutions such as voice over IP," Tamari continued.

A Variety Of Models For All Enterprise Needs

The INVISION  family  features two key product lines,  the INVISION 100, for the
small and medium enterprise, and the INVISION 410, for the large enterprise. The
product  line offers a variety of standard  configurations  to meet the needs of
enterprise customers looking for an off-the-shelf product, from a small business
with only a few end points, all the way up to large,  Fortune 1000 installations
supporting dozens of end points over a converged broadband IP network which also
has ISDN-based legacy end points.

The  entire   INVISION   product  line   features  full  IP  and  ISDN  support,
plug-and-play  functionality,  and complete  address  resolution  for simplified
dialing.  The product  line also has an enhanced  video option that enables rate
matching  and screen  layouts of up to 13 (INVISION  100) or 16  (INVISION  410)
video users.

All products feature the integrated functionality of a gateway,  gatekeeper, and
multipoint  conferencing  bridge. The INVISION 100 comes in either a four BRI or
one PRI  configuration.  The four BRI (INVISION  100/4b) supports a mix of up to
eight voice only calls (@ 64 Kbps), 12 multipoint sessions over IP and ISDN, and
one  conferencing  or  gateway  port (@ 384  Kbps).  The one PRI unit  (INVISION
100/1p)  supporting 23 voice only calls (@ 64 Kbps),  12 multipoint  over IP and
ISDN, and three conferencing or gateway ports (@ 384 Kbps). The INVISION 410 has
four PRIs,  supporting 92 voice only calls (@ 64 Kbps),  21 multipoint  sessions
over IP and ISDN, and fourteen conferencing or gateway ports (@ 384 Kbps).

The INVISION  product  family also  includes an  integrated  network  management
system and end-user conference control capability with intuitive, Web-based user
interfaces.  Finally,  INVISION enables a global view and control of the system,
including  IP  bandwidth   consumption,   ISDN  use,   current  calls,   ongoing
conferences,  and  complete  control  over  voice  and video  traffic  bandwidth
management.

Availability

The  INVISION  100 is  available  for  order  today.  The  INVISION  410 will be
available in early Q1 of 2003.
